Even in the event of large power supply variations, this LT1009CD voltage reference power management device from Texas Instruments can produce and maintain a precise DC voltage. With an output that has a voltage of 2.5 V, this is power management at its best. It has an initial accuracy of 0.2%. Users like the load regulation of 10mV. This voltage reference circuit supports shunt topology. In order to ensure parts aren"t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This voltage reference circuit has a minimum operating temperature of 0 °C and a maximum of 70 °C. It runs with a maximum temperature coefficient of 25ppm/°C.
